Fenn Wing Paddle

I recently purchased a Fenn 1 Wing Paddle with the new lever lock. So far the paddle is working well for me but I'm having a little trouble adjusting the locking mechanism.

I'm trying to figure out how to adjust the lever lock so that it fits tighter around the ferrule. Not sure which screws adjust the friction on the clamp.

Anyone have any experience they can share with this?

It should be something like this:

Flunder,

Thanks for the response. I'm familiar with this process since I have two Epic Wings. The lever lock on the Fenn Wing is slightly different. From what I've seen, there aren't many Fenn Wing paddles in the States. I've never seen a lever lock like this.
